LTC488/LTC489

Quad RS485 Line Receiver

FEATURES

DESCRIPTION

The LTC^®488 and LTC489 are low power differential bus/

line receivers designed for multipoint data transmission

standard RS485 applications with extended common

mode range (12V to –7V). They also meet the require-

ments of RS422.

Low Power: I = 7mA Typ

Designed for RS485 or RS422 Applications

Single 5V Supply

–7V to 12V Bus Common Mode Range Permits 7V

Ground Difference Between Devices on the Bus

60mV Typical Input Hysteresis

The CMOS design offers signiﬁcant power savings over

its bipolar counterpart without sacriﬁcing ruggedness

against overload or ESD damage.

Receiver Maintains High Impedance in Three-State or

with the Power Off

28ns Typical Receiver Propagation Delay

Thereceiverfeaturesthree-stateoutputs,withthereceiver

output maintaining high impedance over the entire com-

mon mode range.

Pin Compatible with the SN75173 (LTC488)

Pin Compatible with the SN75175 (LTC489)

The receiver has a fail-safe feature which guarantees a

high output state when the inputs are left open.

APPLICATIONS

Low Power RS485/RS422 Receivers

Both AC and DC speciﬁcations are guaranteed 4.75V to

5.25V supply voltage range.
